Summary: In the context of surface-enhanced fluorescence sensors, plasmonic gratings are gaining significant attention. The features of the grating can control plasmonic modes, thereby strongly affecting the fluorescence response. This study focuses on using a buffer solution flowing across the active surface of the grating to mimic real measurements. By altering the refractive index of the surrounding medium, the resonance conditions are modified, resulting in a shift in the spectral features and a reshaping of the fluorescence emission in terms of spectral weight and direction.

Summary: Controlled orientation and alignment of rod-shaped plasmonic nanoparticles can dynamically modulate the nonlinear optical response of gold nanorod suspensions, enhancing fluorescent signal detection and revealing optical nonlinearity effects. The combined action of optical force-induced nonlinearity and electric field-induced nanorod orientation leads to new possibilities for engineering nonlinear plasmonic soft matter and detecting low-concentration fluorescent samples.

Summary: This study investigates the evaporation process of plasmonic nanofluids (PNFs) through experiments and simulations. The results show that the combined effect of localized surface plasmon resonance (LSPR) and thermal diffusion can heavily promote the evaporation of PNFs. It is also found that the localized electric field has a significant impact on the evaporation process, especially in the initial stage when the particle temperature is low. This study provides new insights for understanding the evaporation process of PNFs comprehensively.

Summary: This study demonstrates for the first time that additional poling at room temperature of a soda-lime glass can significantly increase its optical second harmonic signal. The observed orientation of hydrogenated dipoles near the glass surface is found to be responsible for the nonlinear behavior of the glass. This finding has implications for molecular physics and electrodynamic studies.

Summary: The quasi-cubic Ag/AgCl plasmonic photocatalyst synthesized through a simple method demonstrated high efficiency and stability in the complete oxidation of nonpolar greenhouse gas methane. Experimental and simulated calculations revealed that the surface plasmonic resonance effect of Ag nanoparticles enhances the adsorption of methane by inducing molecule polarization. This work offers a new direction for exploring other plasmonic photocatalysts in the photo-oxidation of nonpolar gaseous molecules.

Summary: Recent experiments have shown the possibility of tuning the transport properties of metallic nanosized superconductors through a gate voltage, sparking renewed debate on the interaction between electrostatic fields and superconductivity. The study provides conclusive evidence for the electrostatic-field-driven control of the supercurrent in metallic nanosized superconductors, and highlights the need for a novel theory to describe the nontrivial interaction of static electric fields with conventional superconductivity.

Summary: By theoretical exploration, we have discovered high-performance hot spots in the system of Au@SiO2 nanocube dimer on Au film, including large-area hot spots at the intergap between nanocubes, ultrahigh-enhancement hot spots on corners of Au core, and array-type hot spots at the interface between nanocubes and film. The coupling modes have been efficiently manipulated by changing the thickness of the shell and arrangements of nanocubes. These findings inspire and guide the design of advanced nanostructures, opening opportunities for the development of devices such as photodetectors, biosensors, nanolasers, and imaging sensors.

Summary: This study experimentally demonstrates that strong collective resonances can be generated by coupling a metasurface to an optical waveguide, and explores the effect of this waveguide-assisted collective interaction on second-harmonic generation. The experimental results show an 8-fold enhancement for the transmitted second harmonic compared to incoherent collective scattering, and simulations predict a 100-fold enhancement for the second harmonic confined inside the waveguide.

Summary: In this study, a series of plasmonic array structures with different unit numbers were fabricated using focused ion beam (FIB) technology. The effects of the array structures on optical response were investigated using photoluminescence (PL) and surface-enhanced Raman spectroscopy (SERS). It was found that the array units outside the excitation spot still have a significant impact on the optical response, due to the loss of propagating surface plasmon polaritons (PSPPs) outside the excitation point caused by the finite array boundary. This research advances the understanding of near-field and far-field optical behavior in finite-size array structures, and provides guidance for designing highly efficient photonic devices.

Summary: In the presence of strong background rotation, the velocity field tends to become quasi-two-dimensional, leading to an inverse energy cascade. Recent findings show that the radial velocity profiles of axisymmetric cyclones and anticyclones are described by a specific equation, but this theory did not account for boundary effects. The study demonstrates that for typical experimental conditions, the damping of the condensate is determined by linear Ekman friction associated with no-slip conditions at the lower and upper boundaries.

Summary: The study focuses on time-averaged properties of coherent vortices in two-dimensional turbulence, classifying weak perturbations as waves of condensate propagating in the radial direction. The dispersion law and propagation length of these waves are dependent on the radial position inside the vortex flow, with variations between saturated condensate and viscous condensate cases.
